VAPOR-BURNIN G- LAMP.

To all whom it may concern:

Be it known that I, EDWARD J. PARSONS, a citizen of the United States,residing at Mount Sterling, in the county of Van Buren and State ofIowa, have invented a new and useful Vapor-Burning Lamp, of which thefollowing is a specification.

This invention relates to lamps of the type in which a volatilehydro-carbon is vaporzed and the heat from the ignited vapor used torender a mantle incandescent.

One object of the invention is to provide a means for pre-heating theliquid hydrocarbon before it passes into the vaporizing chamber.

Another object of the invention is to provide a means whereby thevaporized hydrocarbon may be kept in a heated state and prevented fromcondensing.

l/Vith the above and other objects in view as will be hereinafterapparent the invention consists in certain novel arrangements ofdetails, and combinations of parts, hereinafter fully described,illustrated in the accompanying drawings and specifically set forth inthe claims.

In the accompanying drawings, like characters of reference indicate likeparts in the several views, and: Figure 1 is a perspective view of lampconstructed in accordance with this invention. Fig. 2 is a verticalsection through the axis of such a lamp. Fig. .3 is a detailed sectionshowing a mixing valve for use with this type of lamp.

The lamp is suspended by means of a tube or pipe 10 provided at itsupper end with a suitable means of suspension as a ceiling plate, hookor the like. This pipe 10 is brazed or otherwise rigidlyv secured to ahollow ball 11, being closed off from the ball by means of a partition12. Through the partition l2 passes one end of a tubular wire 13. Theupper end of the tube 10 is in communication with a suitable source ofhydrocarbon under pressure by means of the tubular wire 14.

Brazed or otherwise secured to the ball 11 are a pair of oppositelydisposed downwardly curved tubes l5 and 16 so arranged as together toform an arch. The lower end of the tube is valved as indicated at 17 andthe tubular wire 13 passes down this tube 15 and through the closedbottom 17 to a needle valve 18 of any preferred form or construction.Upon the lower end of the Specification of Letters Patent. Applicationfiled June 30, 1908.

Patented May 4, 1909. Serial No. 441,185.

tube 15 is mounted an air valve comprising a ring 19, whereon isrotatably mounted a sleeve 20, both body and sleeve being prorided witha series of perforations so that the amount of air admitted may beregulated by turning the sleeve upon the body. Atthe lower end of thetube 1G is a .mixing valve comprising a bell 22, screwed on the tube sothat it may be moved up and down by rotating it in one direction or theother, and a fixed nozzle 23 screwed on an elbow 21 mounted on the endof the vaporizing tube 33 hereinafter to be described.

A short tube 26 is brazed or otherwise secured to the hollow sphere 11.and extends downwardly therefrom. Screwed upon the tube 2G is a verticaltube 27 having a reduced lower end, as seen at 28, the said lower endbeing provided` at its outlet with a suitable screen 29. Upon the tube2T is mounted a heat bell 30, heilig' arranged to slide longitudinallyof the tube and held .in position at any desired point by means of a setscrew 3l.

Between the needle valve 1S and the elbow 2li is located a generatortube 33 preferably packed with some such material as asbestos or thelike, as at 32. The generator tube 33 is of less diameter than the tube27 and passes through that tube, being screwed therein. Upon the tube 33and arranged on either side of the tube 27 is a pair of lock nuts 34.These lock nuts are for the purpose of firmly bracing the tubes 27 andt0- gether.

lvlounted on the reduced portion 2S to the tube 27 is a sleeve carryingan inverted mantle 36.

Depending from the tube 33 is a globe ring 38, a globe 39 being held ina suitable position therein by means of set screws 40. This globe isopen at. the bottom to permit any excess of liquid hydrocarbon fromaccuniulating therein and breaking the globe when the lamp is lighte( Ashade supporting ring itl encircles the tube 32 beingl suitably bracedby means of inclined arms 42. Carried in the shade supporting ring 41 isa shade 43 which may be of any desired form or color.

lV hen this lamp is lighted it will be noted that the tube 13 issurrounded by a body of hot air and that any liquid hydro-carbon passingthrough that tube receives a preliminary warming up so that when itpasses through the needle valve 18 into the vaporizing tube 33 it is incondition for complete vaporization. By reason of the vaporizing tube 33passing through the tube 27 there is provided a zone of relatively greatheat in the middle of that tube and the vaporizing oi a liquid passingthrough that tube is accomplished much more effectively than 'where theheat rises freely and unconned. tis further to be noted that by means ota proper adjustment ot the bell, the tubes may be kept het so that thevaporized hydro-carbon will not condense in either ot them.

It is thus seen by this method of construc tion an extremely ei-icientand useful lamp ot the kind describen is produced and that this lamp isfurther symmetrical in form and pleasing in appearance.

lt is obvious that minor changes may be made in the form and proportionsof this invention without departing from the material principlesthereof.

Having thus described the invention, is claimed, is l l. ln a lamp, avaporizing tube, an arch tube disposed above the vaporizing tube andprovided with an unobstructed interior what chamber extendingapproximately the entire length of said arch tube, a partition betweenone end of the arch tube and vaporizing tube, a mixing valve between theother end of the arch tube and the vaporizing tube, a supply pipe heldin the arch tube in communication with the vaporizing tube, a mantle,and a tube extending from the arch tube to the mantle.

Q. In a lamp, ahorizontal vaporizing tube, an arch tube disposed abovethe vaporizing tube and provided with an interior unobstructed chamberextending the entire length of said arched tube, a partition between oneend of the arch tube and the vaporizing tube, a mixing valve between theother end of the arch tube and the vaporizing tube, a valve controlledsupply pipe held in the iirst mentioned end of the arch tube incommunication with the vaporizing tube, a mantle, and a vertical tubeextending from the center of the arch tube to the mantle.
